  1. The cultural conditions such as temperature, fermentation period and the compound of medium are studied. the result of test show that suitable factors for both bacterium to grow and active substance to produce are 28, 200rpm and 72 hours. the bacterium is gotten through centrifuge with 8000rpm for 20min. then the bacteria is diluted and colophony named s - 8 is put into and used to absorbed active substance for 4 hours

    對該菌株發酵條件的研究表明：該菌株用馬鈴薯葡萄糖液體培養基發酵培養， 28 ， 200rpm搖瓶中振蕩培養72h可獲得高活性的發酵產物，用蘇雲金芽孢桿菌hd - 1做指示菌，將發酵液稀釋40倍生測仍可形成明顯的抑菌圈。
  2. The biological characterization and the absorption capacity of a myxobacterium nust03 for the heavy metal is investigated. an active metabolite is separated and purified from the fermentation by the nust03

    研究鹽土粘細菌nusto3菌株的形態結構、生理生化特性和吸附重金屬的能力並分離純化其胞外活性物質。
  3. Optimum fermentation conditions for insecticidal active substances from xs904 strain and its physical and chemical properties

    904菌株發酵條件的優化及其殺蟲活性物質的理化特性
  4. Although sds - page displayed that there were several protein bands in the sample after 16h fermentation, enzymatic active stain demonstrated that there was only one band during the whole fermentation period, indicating that there is only one kind alkaline protease in the fermentation liquid

    對發酵液進行sds - page和蛋白酶的活性染色分析表明，發酵液中的蛋白質種類不多，且只含有一種堿性蛋白酶。該發酵液所含蛋白酶活性能夠被絲氨酸蛋白酶抑制劑pmsf ， dfp完全抑制。
  5. Induced either by iptg or l - tryptophan in the absence of easily metabolized carbon such as glucose the strain bl21 ( de3 ) / pet28c - tnaa can express tryptopanase. the fermentation conditions were optimized respectively. in the presence of glucose and iptg as induce agent, the concentration is the crucial factor for expression of active tryptophanase. if the iptg concentration is less than 0. 2mm, the optimum temperature is 37 lower temperature is necessary to obtain active tryptophanase in the case of higher concentration of iptg

    用iptg誘導表達實驗結果表明：利用t7啟動子在胞內能表達出有活性的酶； iptg與溫度的合適組合可以得到較高活性的色氨酸酶，在0 . 2mm以下濃度的iptg誘導時， 37是最適溫度，而用較高濃度的iptg誘導，低溫是表達有活性的色氨酸酶的必要條件，而且誘導時間要短。
  6. As a result, the broth of cordyceps militaris fermentation contained antimicrobial active substances

    蛹蟲草發酵液中具有抗菌活性物質。
  7. Therefore, a - amylase has been used widely in many industrial fields, such as glucose production, beer brewing, fermentation trade, textile industry, and so on. the study on a - amylase is one of the most active fields in enzyme industrial fields. with the development of biotechnology, more and more scientists and researchers attempt to use dna shuffling technology to breed, screen and even " create " new a - amylase genes with higher activity and other new characters

    設計引物時，上下游引物5 』端分別添加了kpn和bamh酶切位點，克隆得到的基因片段和質粒載體都用kpn和bamh進行雙酶切后，進行酶連、轉化、篩選得到陽性重組子，經過藍白斑驗證、單酶切驗證、雙酶切驗證、 pcr驗證等一系列的驗證后進行測序。
